0. string
XML Format	In the XML format, this property has the namespace `urn:hl7-org:v3`.
2. string.id
Control	0..0
4. string.extension
Control	0..0

Guidance on how to interpret the contents of this table can be found here

0. string
Definition	A sequence of Unicode characters
Short	Primitive Type string
Comments	Note that FHIR strings SHALL NOT exceed 1,048,576 (1024*1024) characters in size
Control	0..*
Is Modifier	false
XML Format	In the XML format, this property has the namespace `urn:hl7-org:v3`.
Summary	false
Invariants	ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
2. string.id
Definition	unique id for the element within a resource (for internal references) Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
Short	xml:id (or equivalent in JSON)Unique id for inter-element referencing
Control	0..01 This element is affected by the following invariants: ele-1
Type	string
Is Modifier	false
XML Format	In the XML format, this property is represented as an attribute.
Summary	false
4. string.extension
Definition	An Extension May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and managable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
Short	ExtensionAdditional content defined by implementations
Comments	There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
Control	0..0*
Type	Extension
Is Modifier	false
Summary	false
Alternate Names	extensions, user content
Invariants	ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (extension.exists() != value.exists())
